What US foreign policy doctrine did bush promise to enforce?

President George W. Bush promised to enforce the doctrine of preemption as a key aspect of his foreign policy. This doctrine asserted that the United States had the right to take military action against perceived threats before they could materialize, particularly in the context of combating terrorism and preventing the proliferation of weapons of mass destruction. This approach was notably articulated in the context of the 2002 National Security Strategy and justified the invasion of Iraq in 2003.
